T (LZ'Z'lwhem timmy Concern: I' f -A Beit known that I, WILLIAM H. `MINER,"a

` eitizen et the United stetee, residing in ohicago, in'the county ofv Cook and State of Illinois, have invented a-new and useful Improve- 1 ment in Tandem -Springv Draft- Riggingl for Railway-Cars,ofwhich the followingis a specipassenger-cars. A

My invention consistspm the novel construc- I5 fication.

e Myinv'ention relates to tandni-sfpring draftrigging for railway-cars.

My inventionis an improved tandem-spring draft-rigging specially designed for use upon tion of parts and devices andin thefnovel combinations of parts and devices herein shown and describedandspecified in the claims.

tion, of a draft-rigging embodying my inveny'- i In the accompanying drawings, forming' part ofthis specification', Figiire 1 is a side elevation, partly in .longitudinal vertical section; Fig. 2 is a plan view partlyin horifzontal section. Fig. 3 is an'enl'arged crosssection on line 3 3 of Fig. l. Fig. 4 is a detail bottom View of one'of the side plates or stop-castings. Fig. 5 is' a detail top view of the abutment-block between the two middle followers, and Fig.'6 is a central vertical sectional-view of one yof the-followers. 4

In the drawings, A A represent longitudinal sills 'of a passenger-cari A A', the metal draft-sills; A2 A3, cross-sills, and A4 A5 the-'front and rear carry-irons.

B is the coupler having'the customary integral draw-bar Bjand extended draw-bar B,

preferably formed ofwrought-steelbars or plates stiffened and strengthened by rivets or studs C is the draw-bar strap or-yoke, pivotalLv"4 connected at its front end to the rear end of the draw-bar extension B2 bythe'pivot-pin b',

strap or yokeC has bends orv shoulders c c therein near its front end to engage the front follower F, and a bend erv vloop c' at its' rear endpto engage the rear follower F3, and a filler or abutment-block C near-'its middle-to enl gage the two middlefollowers' F -The abutment-block C is securedto the pocket The. draw-barstrap or yoke C by rivets c2, e'xtendingfthrough- 'the yoke, the block being made thick enough longitudinally to accommodate tw,o' rivets,

thus. greatly adding'to the strength and rigidity of the abutment-block. l

D d and D d are the tandem springs, one set of springszbeing between each pair of followers F F and F2 F3, so that both tandem springs will be compressed under either pull-4 v ing or buiing strains.

'Gr Gr are the side plates @stop-castings. Each of these stop-castings is furnished with three stops g g g2 for the followers to abut against under either pulling or buffing strains.

Each of the stop-castings'Gr is provided with a horizontal Harigel or web g" to inclose or fit over the Lipper edges of the 'followersfandform guides for the draw-bar pocket strap'or yoke AC, which iits between the two stop-castings G G. lEach of the stop-castingsjG is also furnished witha horizontally -projecting flange or web fg, which fits under the lower fla-nge a of the -metal draftbeamjoi" sill Ai and'is rigidlysecured thereto'by the rivets g5. `The stop-casting flange g4 also has an upturned "shoulder g, forming, in connection with the shoulder g7, a seat Ito receive the draft-beam flange (t, and thus more securely unite the stop-casting Gr tothe metal draft beam or sill A. Each of the stop-castings Gris also provided with upright braces g8 to strengthen the horizontal flanges or webs g4. Each of the stop-castings G is further provided with upwardly-projecting lugs g", which fit against and are-secured to the upright web a"V vof the' metal draft beam or sill A by the rivets gl". The stop-casting Gris thus secured to the metal draft beam or sill by rivets extending, horizontally through its upright web' and vertically through its horizontal lower angethus affording a very strong and secure attachment `by reason of the stop-casting flange g4, which projects under and fits against the bottom ange a of the metal draft-beam, and the'lugs gg, which t against the linnerside of: theiinetal V draft-beam;
